Abstract

Abstract

Based on approximately solving diffusion equation in node,a series of reconstruction methods are developed for NGFMN code.These methods are categorized by hyperbolic functions,boundary conditions and the order of Legendre polynomials utilized in equation solving.2D IAEA and 2D BIBLIS benchmarks have been solved.The numerical results are compared with those from CITATION,and the reconstruction method with smaller errors is selected.
